IMPROVEMENT IN WASHING-MACHINES.

I Specification forming part of Letters Patent N 0. 138,110, dated April 22, 1873 application filed March 22, 1873.

To all whom it may concern:

Be it known that I, NELSON 0. WILooX, of

Omaha, in the county of Douglass and State of Nebraska, have invented a new and useful Improvement in Tub Washing-Machines, of which the following is a specification:

The object of this invention is to pgovide cheap, convenient, and eflicient means for washing clothes; and the invention consists in an extension bed for adapting it and fastening it to tubs of different diameter, and in a corrugated spring-rolleroperatingin combination with one or more stationary rollers and springs, the construction and arrangement of parts being as hereinafter described.

In the accompanying drawing, Figure 1 represents a sectional side elevation. Fig. 2 is a vertical cross-section of Fig. 1 taken on the line :0 a. Fig. 3 is a section of Fig. 2 taken on the line ;1 y.

Similar letters of reference indicate correspondin g parts.

A represents an ordinary wash-tub to which my machine is attached. B is the base to which are attached the standsO and D. The base B is made adjustable as to length by means of the sliding piece E, which is grooved into the base and slotted, as seen in Fig. 2.

F is a bolt in the base, which passes through.

the slot. The length of the base is thereby adjusted to suit tubs of difierent diameters. On the end of the base B and on the outer end of the piece E there is a transverse piece, G, which catches over the rim of the tub,'as seen in Fig.1, to keep the machine in place. H on pivots, with is the bed-roller revolving its sides inolosed by the blocks I I, as seen in Fig. 2. There may be four of these rollers. J is the corrugated roller, which is revolved by means of the crank K. The inner sides of the stands 0 and D are recessed from the base to the top, and in these recesses are placed the spring-holders L L, in which the journals of the two rollers revolve. These holders are each in two parts, the bed-rollers revolve in the lower part, and the corrugated roller has its bearing between the two, as seen in Fig. 2. The holders L L are rebated or grooved on their sides, and the parts of each are confined together by the elastic springs N. These springs are simple rings or bands of rubber which surround the holders L L. The corrugated roller is placed directly over and nearly in contact with the bed-rollers.

It will be seen that when the clothes are made to pass between the two rollers the corrugated roller must be forced upward, but that motion will be resisted by the springs N,- and consequently the clothes will be squeezed by a force proportioned to the strength of the springs.

The recesses in the stands and the shape of the pieces L L are tapering from the base up, representing a longitudinal section of a truncated pyramid, but they may be of other form. The crank journal of the corrugated roller passes through the stand in a vertical slot, so that it plays freely up and down. By means of this washer the clothes are repeatedly pressed and rinsed, and this is the true principle of washing clothes.

The lower portions of the spring-holders L L are rigidly attached by screws to the stands 0 D, but are readily detached by taking out the screws for renewing the springs or other purposes. The blocks or guides l I prevent the clothes from getting under the bed-rollers and guide the clothes between the rollers.

Having thus described my invention, I. claim as new and desire to secure by Letters Patent- A tub washing-machine, consisting of an extension base B E, bed-roller H, corrugated roller J, stands 0 D, spring-holders L L, and springs N, when the same are arranged to operate as shown and described.
